Lighting | little knowledge of the factors affecting the service life of heating type fluorescent lamp have? - China lighting network

Preheat type fluorescent lamp in the startup phase electrode bombarded by the much more serious than light phase, frequently open to turn off the lights, will shorten the life of the fluorescent lamp. Life is always in every switch light 3 h. Every light 1 h switch, the light will shorten the service life. Every switch to extend the time of ignition point, to extend service life. Typical ratio relationship is every time I turn on the light flash point 6 h can prolong life 25%; Ignition point 12 h can prolong life 60%; If light continuous ignition point, its life is more than 1 times longer than the standard conditions. In addition, the voltage is too low or too high, not appropriate, the starter temperature is too low, ballast is unqualified or does not match the factors will affect the service life of the lamp. Low voltage power supply or ballast unqualified cause voltage change, current change can cause tubes. 1% of the voltage change, can make the lamp current change 1% 2%. Lamp current is increased by 1%, and shorten the life 1. 7%; Lamp current is too small, the cathode temperature is too low, the electronic powder on the electrode sputtering, life will be shortened.
